Chromaticity effects in microlensing by wormholes

TL;DR

This paper investigates how chromaticity effects caused by finite source size in microlensing events can help distinguish natural wormholes from ordinary lenses through spectral analysis, applicable in galactic and extragalactic contexts.

Contribution

It demonstrates that chromaticity signatures in microlensing can differentiate wormholes from negative mass lenses, offering a new observational method.

Findings

Chromaticity effects are significant in microlensing by wormholes.

Spectral analysis can discriminate between wormholes and ordinary lenses.

Applicable to both galactic and extragalactic microlensing events.

Abstract

Chromaticity effects introduced by the finite source size in microlensing events by presumed natural wormholes are studied. It is shown that these effects provide a specific signature that allow to discriminate between ordinary and negative mass lenses through the spectral analysis of the microlensing events. Both galactic and extragalactic situations are discussed.
